How do you get past the power outage on Pokemon platinum?

i think you go to verity lakefront then there you will fight Jupiter or mars. After that then go to acuity lakefront and you will see your friend had go defeated by Jupiter or mars the go tovielstone city and go to the front of the team galatics hide out and you will see the person you chased from in front of the saffary zone in pastoria city (the man you chase is from team galatic) the he will drop the key then go in the hide out or were you help dawn beat the two galagtic grunts and go throw the maze
